You are given four sources of light each one providing a light of a single colour - red, blue , green , and yellow . Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is $90^{\circ}$ Which of the following statement is correct if the source of yellow light is replaced with that of other lights without changing the angle of incident ?

Question

$\begin{array}{1 1} \text{The beam of red light would undergo total internal reflection} \\\text{The beam of red light would towards normal while it gets refracted through the second medium } \\ \text{The beam of blue light would undergo total internal reflection} \\ \text{The beam of green light would bend away from the normal as it gets replaced through the second medium } \end{array} $
